Quick Verdict
- Triple Yamaha 450 XTOs deliver 55.1 mph, with a published 28.5 mph best cruise at 0.73 mpg and 317 miles of range.
- Two sleeping areas in 43 feet: a convertible island queen forward and a mid/aft stateroom behind a solid-wood privacy door.
- A Seakeeper 6 gyro and Zipwake automatic trim control are standard, as is a 9 kW generator and 16,000 BTU cabin air.
Our Take
The OS 405 is the point in Pursuit's Offshore line where a boat stops being a day boat with a berth in it. What distinguishes it is not the length or the 55 mph — it is one detail on the floor plan: the mid/aft stateroom has a privacy door with a solid wood frame. Somebody can go to bed while everybody else stays up on the bridge deck. Two sleeping areas and a door, at 43 feet, on outboards, with a 2-foot-7-inch draft motors up and a joystick — that is a boat a family uses on a Friday night instead of talking about using.
Pursuit publishes its homework, which is why I am willing to be specific about the trade you are making. The bulletin ran 8/1/2023 at 29,987 pounds with four aboard. Best cruise is 3,500 rpm — 28.5 mph, 38.9 gallons an hour, 0.73 miles to the gallon, 317 miles of range on 90 percent of the fuel. Push to 4,000 and you get 36.5 mph for 294 miles, which is the number most owners will actually run. And read the top of the sheet before you brag about it: from 5,500 to 6,000 rpm the boat gains 0.7 mph and burns another 6.8 gallons an hour. Fifty-four point four is free; 55.1 is vanity. Two other things belong in this paragraph because they cost a fortune to add later and Pursuit fits them as standard — a Seakeeper 6 gyro with certified structural integration, and Zipwake interceptors doing your trim work automatically.
The honest limit is efficiency and it is not small. The OS 355, one step down the line, cruises at a full 1.00 mile per gallon and publishes 348 miles of range against this boat's 317 — you are paying roughly a third of your fuel economy for the extra room. If range is what you are actually buying, buy the OS 355 and do not look back. And be precise about what "two cabins" means here: the forward space is a convertible cabin open to the saloon, the aft one is the real room, and there is one head and one shower for everyone aboard. Two couples who both want a proper stateroom with a door should go and stand in an OS 445 before signing anything.

Frequently Asked Questions
How many people can sleep on the Pursuit OS 405?
Pursuit publishes berths rather than a sleeping-capacity figure for this model, and there are two separate sleeping areas.
The forward cabin has an electrically convertible island-style berth with a queen memory-foam mattress, hinging backrests, a gas-assisted mattress base with storage beneath and a hanging locker. The mid stateroom has a full-size berth, a settee and a solid-wood privacy door — the detail that separates this boat from the OS 355, where everybody sleeps in one space. The bridge-deck teak table converts to another berth.
One head serves both, to starboard, with a separate shower, a solid-surface vanity and a 26-gallon holding tank. Fresh water is 80 gallons.
Pursuit OS 405 or OS 445 — which should I buy?
The OS 445 if you want two staterooms and a bridge-deck galley; the OS 405 if you want the same idea in a boat three and a half feet shorter and 5,426 pounds lighter.
Both run triple Yamaha 450 XTOs at 1,350 horsepower. The OS 405 is 43 feet with the platform, 25,292 pounds dry, and does 55.1 mph. The OS 445 is 46 feet 6 inches, 30,718 pounds, and does 49.2 mph on exactly the same power — you can read the weight straight off that number.
The OS 445 carries 600 gallons of fuel against 482, and 100 gallons of water against 80. If the second stateroom is not going to be slept in, the lighter boat is the quicker and less thirsty one.
How fast is the Pursuit OS 405?
55.1 mph at 6,000 RPM on triple Yamaha 450 XTOs, from Pursuit's own test sheet. The run was made on 8/1/2023 at 29,987 pounds — four people, 481 gallons of fuel, full water and diesel tanks and all optional equipment — on 16-3/8" x 21" XTO propellers.
Nought to thirty takes 12.6 seconds. The triples make 1,350 horsepower, the hull's maximum rating, and they are the only package Pursuit publishes performance data for on this model. Dry weight is 25,292 pounds.
What cruise speed and range does Pursuit publish for the OS 405?
28.5 mph at 3,500 RPM, burning 38.9 gallons an hour for 0.73 miles per gallon and 317 miles of range on 90 percent of the test-condition fuel. That is the best-cruise row.
The sheet is worth reading past that line. At 4,000 RPM you get 36.5 mph on 53.8 gallons an hour for 294 miles — eight more miles an hour for 23 fewer miles of range and fifteen more gallons an hour.
Below 3,500 RPM the numbers fall away sharply: 10.9 mph at 23.6 gallons an hour and 0.46 mpg at 2,500 RPM, because the hull is still pushing water rather than riding on it. On a boat this size, slowing down does not save fuel.
